COPY-HOLDER.

srnolrrcn TION forming part of Letters Patent No. 661,785, datedNovember 13, 1900.

Application filed March 1, 1900- Serial No. 61928. (No model;)

To a) whom it may concern.-

Be it known that I, JOHN BACHELDER, a citizen of the United States,residing at Watertown, in the county of Jeiferson and State of New York,have invented certain new and useful Improvements in Copy-Holders; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

- The invention relates to copy-holders.

The object of the invention is to provide a copy-holder which shall besimple of construction, durable in use, and comparatively inexpensive ofproduction, easily operated, and provided with means by which it may beadjusted to lines different distances apart.

To this end the invention consists in certain features of constructionand combination of parts, which will be hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 is a perspective view of myimproved copyholder. Fig. 2 is a front elevation, on an enlarged scale,of the gear-casing and its inclosed gearing, the cover of the casingbeing removed to more clearly illustrate the parts. Fig. 3 is ahorizontal sectional view through the gear-casing, showing the partstherein in elevation. Fig. 4 is a sectional view taken through thefriction-wheel, the friction-lever,

and the friction-head, and illustrating the re-.

lation of the friction-head with the frictionwheel before theoperating-key is depressed.

Fig. 5 is a sectional view through the side of the gear-casing and thefriction-lever. stop. Fig. 6 is a perspective View of the markerhead,showing it attached to one of the vertical rods of the frame. Fig. 7 isa rear view of the same. Fig. 8 is a cross sectional view through theline-marker, its head, and the screw for securing it to its head. Fig. 9is a detail perspective view of the clamp.

In the drawings the same reference characters indicate the same parts ofthe invention.

1 denotes the supporting-base, 2 the upright frame, consisting of theside pieces 3 and 4 and the top or cross piece 5, and 6 the back of theholder, the upper end of which is hooked around the upper cross-piece ofthe frame and the lower end of which is slotted to receive screws 7, bymeans of which the back is held in place.

8 denotes the gear-casing, which is suitably secured to the base. Theback 6 serves as the front of this casing, and when removed presents toview the mechanism inclosed with in said casing. v 9 denotes afriction-wheel journaled within said casing upon a stud-axle l0 andprovided with a central boss 11, upon which is loosely mounted a lever12, the free end of which is connected with an operating-key 13,projecting through a slot 14 of the base and adapted to be actuated bythe finger.

. 15 denotes a friction-lever pivoted to theouter end of theactuating-lever 12 and extending across the face of the friction-wheelZat'a point to one side of its axis, either below or above, (in thepresent case shown as above,) and provided with a friction-head 16,which is adapted to engage the periphery of the friction-wheel. Thishead has a shank 1-7, which, projects through the longitudinal slot 18in the free end of the friction-lever and is held in proper adjustmentto the pelriphery of the friction-wheel by a nut 19.

i 20 denotes an adjustable stop secured to the side of the casing andadapted to receive and support the free end of the friction-lever andhold it in such a position as to leave a slight space between thefriction-head and the periphery of the friction-wheel when the parts areat rest and permit of an unwinding movement of the friction-wheel.

21 denotes a coil-spring connecting the inner end of the operating-leverto a fixed part 'of the frame. The energy of this spring is Eexerted toelevate the outer end of the lever Zand raise the finger-key upwardafter it has ;been depressed and throw the free end of thefriction-lever downward and upon its stop, in which position thefriction-head is held at a slight distance from the periphery of thefriction-wheel. To limit the throw of the opcrating-lever, Iprovide anysuitable means such, for instance, as an adj listing-screw 22, whichworks upward through the base within the path of movement of theoperating-lever and is provided with a handle-nut 23, by which the screwmay be set after it has been properly adjusted.

24 denotes a brake-spring secured to the 26 denotes the line-marker,which is coir" nected to a head 27, which has a vertical slidingmovement upon the side piece 3 of the frame 2. The head is providedwi'tha spring 28, the free end of which engages the side" piece of theframe 2 and by frictional energy holds the head in its adjustedposition. The end of the marker is bent and provided with a slot 29 tobe engaged by a set-screw 30, which'works into the head and screws themarker thereto.

31 denotes a cord, which is connected to the head and passes through anorifice in the base around'a guide-pulley 32, secured to the un-- derside of the base, and is connected to the periphery of thefriction-wheel.

In operation the manuscript or copy is fas= tened to the back of theholder by the copyclamp and the line-marker is elevated to restimmediately under the first line of the copy. After the first line hasbeen copied by de pressing upon the key-the operating lever is moveddownward. This movement draws the friction-head inward and clamps it tothe periphery of the friction wheel, which will now be rotated adistance corresponding to the distance between the upper end ofthelimiting-screw andth'e lower edge of the operatin glever on thedownstroke of the lever, which abuts against the upper end of saidscrew. This movement winds the cord upon the Wheel and draws the markerdownwardly immediately below the next line. The instant the key isreleased the spring 21 will retract the lever, thus elevating the keyand permitting of the free end of the friction-lever falling, downwardand resting upon its limit-stop, in which position. it is free fromengagement'with the periphery of the wheel, and will thereby permit of areverse rotation of the friction-wheel and a free unwinding of the cordtherefrom in the act'of elevating the marker to bring it under the topline of the next page or sheet to be copied.

From the foregoing description, taken in This clamp is fastened toconnection with the accompanying drawings the construction, operation,and advantages of my improved copy-holder will be readily apparentwithout requiring an extended explanation. It will be seen that thedevice is simple of construction, that said construction permits of itsmanufacture at sniall cost, and that it is exceedingly well adapted forthe' purpose for which it is designed. Y

Various changes in the form, proportion, and the minor details ofconstruction may he resorted to without departing from the principle orsacrificing any of the advantages of this invention. Y

"'Havirig thus described the invention, what is claimed, and desired tobe secured by Let= ters Patent, is* p 1. A copy-holder comprising asupportingbase, a vertically-sl idable line-marker, a fric non-wheel, aflexible connection between the line-marker and the friction wheel, anoperating-lever, a key connected to'said operatingdeve'r, afriction-lever provided with a friction head adapted to engage thefrictionwheel on the downstroke of the key to rotate it, and means forreleasing the head from the periphery of the friction-wheel on theupstroke 'of the key and holding it out of en'- gage'm'ent with saidwheel while the key is in its uppermost position to permit of a reverserotation of the friction-wheel, substantially as and for the purpose setforth.

A copy=holder, comprising the supporting-piece, a vertically-slidingline-marker, a fri'ctiomwheel, a flexible connection between theline-marker and the f ricti'on-wheel, an opcrating-lever, a keyconnected to said operating-le've'r, a friction-lever provided with afriction-head adapted to engage the frictionwheel on the downstroke ofthe key to rotate it, means for limiting the downstroke of the key, andmeans for releasing the head from the periphery of the friction-wheel onthe upstroke of the key and holding it out of engageme'nt with saidwheel while the key is in its uppermost position to permit a reverserotation of the friction wheel, substantially as and for the purpose setforth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
